Well if you're really into D3 now I hope you enjoy the 30 million gold it requires to buy simple upgrades, and inflation is ever increasing so it might be 50 million in another month, and 100 million a month after that. Price of gold was 25 cents for 100k a couple months ago, it is now 65 cents for 1 million, should be a quarter for 10 million in another 6 months or so; fantastic.
I beat inferno without using the Auction House.
Yeah I beat the game much earlier than anyone on this forum I'm sure, that doesn't change how few and far between drops that are actually upgrades are. Diablo 3 might be a good game in 2 or 3 years after numerous patches and balance changes, but its far from it right now. Mediocre D2 clone at best, shame it sold so ridiculously well; one would hope faith in Blizzard's omnipotence wanes over the decade it takes for Diablo 4 to come out.
Put another way I had 25 friends online when D3 launched, now I have 0 consistently. Public games were at 25000 or so a monthish after launch, right now its at 600. I realize people might be completely and utterly oblivious like game reviewers but it's not that hard to see precipitous decline.
